SAMUEL J. SEIFRIED, OF CHICAGO, ILLINOIS, ASSIGNOR TO THE MUNSON TYPEWRITER COMPANY, OF SAME PLACE.

TYPE-WRITING MACHINE.

SPECIFICATION forming part of Letters Patent No. 474,350, dated May 3,1892 Application filed August 14, 1891- Serial No. 402,684- (No model.)

To all whom it may concern.-

Be it known that 1, SAMUEL J. SE1EEIED,a citizen of the United States,residing at Ohicago, in the county of Cook and State of Illinois, haveinvented a new and useful Improvement in 'llype-WVriting Machines, ofwhich the following is a specification.

My invention relates to improvements in type-writers wherein a rotatablesliding typesleeve is employed, and more particularly to improvementsupon the type-writer heretofore patented to me in Letters Patent No.411,066, of September 17, 1889, and No. 446,394, of February 10, 1891.

My improved type-writer has the same general principle and mode ofoperation as the machine heretofore patented to me in the Letters Patentabove named.

The improvements which I have made are designed to simplify theconstruction of the machine, to render it more durable, its operationmore efficient and certain, and to enable it to be more convenientlyoperated.

In my former machine the paper was wound around a paper holder orcylinder to keep the same out of the way of the hammer and the mechanismfor communicating motion to the hammer.

In my present invention the hammer and part of the mechanism forcommunicating motion thereto are mounted upon a goose'neck frameorsupport, so that I can pass the sheet of paper around the hammer orbetween the hammer and the machine proper, thus enabling me to dispensewith the paper-storage cylinder or roller, and thus materially diminishthe cost of the machine, as well as greatly increasing the convenienceof its operation in putting the paper in or out and adjusting theposition of the same.

Another feature of my present improve ment consists in mounting thegoose-neck hammersupporting frame to telescope or slide upon the mainframe of the machine, so that the goose-neck will shut within the latterwhen the machine is not in use, and thus cause the machine to be ascompact as though the goose-neck support for the hammer were notemployed.

Another feature consists in the means for connecting and disconnectingthe hammer operating mechanism which is mounted on the goose-neck framewith that which is mounted upon the main frame by the simple act ofsliding the goose-neck in or out, so that no inconvenience may arisefrom the sliding or telescopic connection of the goose-neck with themain frame.

In my presentimprovement, as will be hereinafter more particularlyexplained, I have also materially simplified the mechanism forcommunicating the necessary rotary and sliding movements to thetype-sleeve from the key-levers, also the mechanism for supporting andoperating the ink-ribbon, and also the general construction of thepaper-carriage.

My invent-ion also consists in the novel devices and novel combinationsof parts and devices herein shown and described, and more particularlypointed out in the claims.

In the accompanying drawings, which form a part of this specification,and in which similar letters of reference indicate like parts throughoutall the figures, Figure 1 is a plan view of a machine embodying myinvention. Fig. 2 is a side elevation. Fig.3 is a vertical section takenon line 3 3 of Fig. 1. Fig. 4 is a vertical section taken on line t 4 ofFig. 1. Fig. 5 is a detail plan view of the key-levers and theirconnections. Fig.6 is a detail side elevation of the key-levers andmechanism for rotating the type-sleeve to change from one case toanother. Figs. 7 and 8 are similar views of the same in differentpositions. Fig. 9 is a detail elevation of the mechanism for communicating the necessary rotary movement to the typesleeve. Fig. 10 is adetail perspective view of a part hereinafter to be described. Fig. 11is a detail perspective view of the goose-neck frame orsupport uponwhich the hammer is mounted. Fig. 12 is a detail cross-section of thecarriage. Fig.13 is a detail elevation of the mechanism for operatingthe paper-feed roller. Fig. 14 is a detail section of the escapementmechanism. Fig. 15 is a detail face view of the escapement-wheel. Fig.16 is a section on line 16 16 of Fig. 7. Fig. 17 is a detail view of thelatch for locking the cap-key lever and figure-key lever in place.

In the drawings, A'represents the frame of the machine. The frame A isfurnished with IOU rubber feet or cushions A and with vertical sidepieces or wings A upon which the main shafts of the type-writer arepivoted or journaled. The frame also has front and rear combs or slottedplates A and A to serve as guides for the key-levers.

B 13 represent the keys, preferably thirty in number, arranged in threetransverse rows.

3 B B are the key-levers for the three rows of keys, pivoted toshafts 1) F12 respectively, and which extend across the frame.

0 is the rotary slidingtypesleeve, furnished with an annular groove 0near its middle and a spline or projection c, which engages thelongitudinal groove 0 in the rotary shaft C, upon which the type-sleeveis mounted. The rotary type-sleeve shaft Chas pivot-bearings c c on theframe of the machine,the pivot 0 being fixed in place by a set-screw cThe type-sleeve O isalso provided with a series of registering notches cat each end, which fit the stop-pins D, with which they engage. Theouter portions of these registering notches c are made inclined orcam-shaped at 0 so that the registering notch a will readily engage thestop-pin and the latter serve to cause the type-sleeve to accuratelyregister both longitudinally and radially with the line of printing andproperly space the letters therein. The type-sleeve 0 preferably hasnine faces or rows of characters, with ten characters in each row orface,-five being on each side of the annular groove 0. The sliding orreciprocating movement of the type-sleeve C on its shaft 0 serves tobring the different characters in each row longitudinally into positionin front of the impression-hammer, and the radial movement of thetypesleeve by the rotation of its shaft C serves to bring each of thecharacters radially into position in front of the impression-hammer. Thekey-levers B of the first row of keys operate simply to slide thetype-sleeve without rotating it, while the key-levers, B of the secondrow of keys operate not only to shde the type-sleeve, but also to rotateit one-ninth of a revolution, and the key-levers 13 of the third row ofkeys operate to slide the type-sleeve and to rotate it one-ninth of arevolution in the opposite direction. On the type-sleeve there are threedifferent cases of type or characters, three rows or faces of thetype-sleeve constituting one case of characters. To bring the second andthird cases of characters on the typesleeve into the field of operation,two keys and key-levers are employed, one to rotate the type-sleeveone-third of a revolution, the other two-thirds of a revolution.

0 is the key and O the key-lever for the cap-case of characters, and Pand P the key and key-lever for the figure-case of characters.

As the same sliding or longitudinal movement of the type-sleeve servesto move it into proper position longitudinally for the characters ofeach of the three faces or rows of characters, the keys and key-leversare arranged in sets of three, one key of each set being found in eachof the three rows of keys, and for the same reason the registering orstop pins D are ten in number,arranged five on each side of the machineor at each end of the typesleeve. The two extreme stop-pins D may befixed to the stationary frame-work of the machine; but the remainingeightf0ur on each sideare necessarily movable, so that they may be movedinto and out of position for engaging the registering notches at theends of the type-sleeve. The necessary one-ninth rotary movement of thetype-sleeve is eommunicated thereto from the key-levers B of the secondrow of keys by means of a bar F, extending across all the key-levers B BB the keylevers B and B being, however, notched or otherwise soconstructed that they will not engage or operate the cross-bar F, andthe necessary one-ninth revolution of the type-sleeve C in the oppositedirection is communicated thereto from the key-levers B of the third roWof keys by a similar bar F, extending across the same, the key-levers Band B being of course notched, so that they will not operate the bar F.The necessary sliding or longitudinal movement is communicated to thetype-sleeve G from each of the ten sets of three contiguous key-1evers BB B by a series of rock-shafts G, ten in number, each having an arm g,furnished with a foot g, which spans the three contiguous keys B B B ofeach set. Five of these rock-shafts G are on each side of the machine,those on one side operatingtomove the typesleeve from its middle ornormal position in one direction and those on the other side in theopposite direction.

It will be observed that the parts which I have thus far enumerated havesubstantially the same general construction and mode of operation as thecorresponding parts of my former patents above mentioned.

The mechanism forcomm unicating the necessary rotary movement to thetypesleeve C or its shaft C consists of the intermeshing gears (J C andswinging segment gear or rack (J mounted upon the pivot-bearing pin 0 ofthe shaft 0. The intermediate gear (J is journaled upon a swinging armor lever C and the gear C is connected directly to the type-sleeve shaft0. The segment or rack ,0 is operated by the case-key levers O and Pthrough the connecting-link P having a pin at its lower end, whichengages the levers O P. The cap-lever 0 serves to turn the segment 0sufficiently to cause the typesleeve to rotate one-third of a revolutionand the figure-lever P sufficiently to cause' the type-sleeve to rotatetwo-thirds of a revolution. The key-levers B of the second row of keyscommunicate the necessary one-ninth rotary movement to the type-sleevethrough the cross-bar F, connecting-link f f, leverarms h h, androck-shaft H, one of the arms h of the rock-shaft having a cam h, whichengages a pin 713 on the bent lever K, which is connected by a link 70with the lever or arm on which the gear 0 is journaled. The necessaryone-ninth rotary movement of the type-sleeve in the opposite directionis communicated thereto from the third row of keys ]3 through the bar F,links f, rock-shaft H, having arms 7L2, one of said arms 72/ having acam h which engages the pin 713 on the opposite side thereof from thelever-arm h, thus moving the arm 0 in the opposite direction. As shownin Fig. 9, the lever h is represented as being raised or partiallyraised by its link f, and thus in the act of causing its cam h toactuate the bent lever K. It will be understood that the lever h returnsto its normal position when the other lever 72/ and its cam 71,3 areoperating the bent lever K. The segment gear or rack C is preferablyconstructed with a hub C upon which the gear C and lever-arm C arejournaled. The connection between the gear 0 and the type-sleeve shaft 0preferably consists of an arm 0 on the shaft C, which fits in a slotteddisk 0, se-. cured to the gear C 0 is a stop, which engages a stop-pin Oon the swinging arm C to. approximately limit the throw of said arm ineither direction to insure the proper engagement of the registeringnotches c on the type-sleeve with the stoppins D.

The necessary longitudinal movement is communicated to the type-sleeve Cfrom each set of three keys, as before stated, through the rock-shaft G,having arm g, furnished with foot g. Each of these ten rock-shafts G isalso furnished with an arm 9 which engages the horizontal cam-shapedlever J, the end of the leverJbeing curved or cam-shaped at 7" andengaging a pin it on the upright lever N, the upper end of which isfurnished with a pin it, which engages the annular groove 0 in thetype-sleeve. This upright lever N is made hook-shaped or curved,substantially as indicatedin the drawings, so that it will not interferewith the lower web of the ink-ribbon. The series of arms 9 on the rockshafts G move the type-sleeve longitudinally different distances,according to their distance from the pivotj of thelever J. The stop-pinsD are connected to and operated by the arms 9 of the rock-shaft G.

M is the rock-shaft to which is secured the hammer-operating lever M;This hammeroperating lever M has feet or wings m m, which project overthe arms 9 on the rockshaft G, so that the lever M will receive motiontherefrom. The lever M, with its wings 117., also serves as areturning-lever to return the stop-pins D and their operating-arms g totheir normal position after each impulse. This is done by a spring 1vconnected to a lever M on the rock-shaft M, and which engages an arm m,rigidly secured to the rockshaft. The hammer-operating lever M is alsoprovided with a cross-bar or bridge m having inclined or cam-shapedfaces m m terminating in a registering notch m which engages the pin 41on the lever N, which slides the type-sleeve, and thus serves to returnthe typesleeve longitudinally to position after each impulse. Therock-shaft M is further provided with a returning arm or lever M havingadouble-inclined or earn-shaped notch m that engages the operating-pin 7cof the bent lever K, and thus serves to return it and the type-sleeveoperated therefrom to position af ter each impulse.

The hammer-operating arm or lever M is furnished at its extreme end witha pin or projection m, which engages the hook-shaped or slotted arm 1",through which motion is communicated to the hammer R. The pin m has apointed or conical end to insure the ready engagement of the same withthe slotted arm r.

R is the goose-neck frame orsupport upon whichthehammerRismounted.Thisgooseneck frame slides or reciprocates on suitable guides a on theframe of the machine. The hammer R is secured to a rock-shaft R which isjournaled in suitable bearings R on the upper limb of the goose-neck R,and motion is communicated to this rock-shaft from the slotted arm 7'through the rock-shaft R arm R link It, and arm R The slot 1'" of thehammeroperating arm 1' is widened at its outer portion 4*, so that thehammer, when an impulse is imparted to it from the pin m in the lever Mengaging the slotted arm 4", will be free to rebound after striking thetype-sleevethat is to say, the pin m on the lever M imparts at the firstportion of its stroke a forward or striking impulse to the hammer R, themomentum of the hammer after thus receiving the impulse carrying itforward untilitimpinges against the type-sleeve. When the hammerimpinges against the typesleeve, it is free to rebound, because at thistime the pin m on the lever M is not in engagement with the edge of thewidened slot 7" in the operating-arm 0". By this arrangement the hammersimply delivers a blow while freely suspended from its pivot and free torebound. The hammer-head r is detachably secured to the hammer R bymeans of a set-screw r so that it may be conveniently and quicklyremoved and replaced by another removable hammer-head when desired fordifferent kinds of work. For most uses ahard- IIO rubber hammer-headshould be employed;

but for making a great number of manifold copies a harder or metallichammer-head is preferably used. The hammerhead r is made star-shaped, sothat it has a numberpreferably five-of operatingfaces r By thus makingthe hammer-head star-shaped with a number of operating-faces itsdurability is greatly increased. The central hole through thehammer-head, by which it is secured in place on the hammer bytheset-screw r serves, owing to the star shape of the hammer-head, to fixit properly in place for all its faces. By simply slipping thegoose-neck R out on its guides a the slotted operating-arm r is broughtinto engagement with the conicalv on one spool and then on the other.

pointed pin m 'on the hammer-operating lever M. A set-screw R serves tofix the goose-neck ham mer-snpporting frame in place in its extendedposition. lVhen the machine is not in use or is being carried about, thegoose-neck frame R is simply telescoped or slipped back on its guideswithin the main frame A, so that the machine as a whole has then noadditional width.

By employing a goose-neck frame or support for the hammer andcommunicatingmotion thereto around the goose-neck I am enabled to'passthe paper between the upper and lower limbs of the goose-neck frame, andthus around the hammer or between the hammer and the machine proper,thus enabling me to dispense with the paper-storage cylinder or holderaround which in my previous machine the paper was wrapped or wound.

Q and Q are the inking-ribbon spools. The shafts Q Q are journaled on aportion A of the main frame. The bridge portion A of the main frame issecured in place by screws. This bridge portion A of the frame has adepending standard A, upon which is journaled the ratchet q, throughwhich motion is communicated to the spools fromthe pawl q' on thehammer-operating lever M. the depending arm or bracket A on the bridgeportion A of the frame is a locking-pawl g which likewise engages theratchet and serves to prevent any back motion thereof. This locking-pawlg has a weighted arm g to hold it in engagement with the ratchet-wheelq. Theshafts Q Q of the ribbon-spools are each furnished with a gear qor q, to one of which motion is communicated from the ratchetwheel by agear q thereon, which meshes with an intermediate gear journaled on aswinging arm or lever g pivoted to the shaft of the ratchet-wheel.Secured to the gear q" is a smaller gear g that meshes with one or otherof the .gears on the spool-shafts Q Q according as the lever g isshifted forward or backward. The lever g is furnished with a pin whichengages a latch Q t/O hold the lever g in position. The ribbon (1 passesfrom one spool Q around the type-wheel O to the other spool Q. Byshifting the lever g from one position to the other either spool may bedriven, thus winding the ribbon e shafts Q Q of the ribbon-spools aremade long enough so that the spools may be slipped into differentpositions longitudinally thereon, and thus bring different strips orportions of the ribbon in line with the impressionhammer. By thisadjustment of the ribbonspools on their shafts, in connection with thewinding or traveling movement of the ribbon, every portion of the ribbonmay be utilized.

Back of the type-sleeve C, I provide a ribbon-guard Q having an openingQ therein for the face of the hammer to strike through. Thisribbon-guard serves to keep the paper from coming in contact with theribbon except at a point where the hammer-head strikes Pivoted to.

the same. The ribbon-guard Q is furnished with a pointer Q atits uppermiddle portion to indicate the point on the printed line where thehammer strikes. This is of service in making corrections and inadjusting the paper-carriage to position for work. The ribbon-guard Q issecured to a horizontal arm Q attached to a bracket Q on the main frame.The bracketQ is also furnished with a horizontal guide-arm Q to supportthe ribbon-guard at its lower edge and prevent the same coming incontact with the type-sleeve. This horizontal arm Q is also of serviceas a guide for the ribbon.

T is the paper-carriage. It slides on suitable guides a a on the frameof the machine, the guides or the carriage being furnished withfriction-rolls t to cause the carriage to move easily. The carriage isfurnished with a rack 'I', which engages the escapement mechanism.Pivoted to the carriage is a swinging frame T upon which the paper-feedroller T is journaled. The shaft T of the paper-feed roller is furnishedwith'a thu mb-piece or handwheel T at one end, by which the feed-rollermay be turned by hand to adjust the paper in position when desired. Atits opposite end the paper-feed roller is provided with a ratchet-wheelt and a gear-wheel 25 The gearwheel 25 meshes with a gear t secured tothe ratchet-wheel 25 which is operated by a pawl t pivoted to thepawl-lever t. The pawl-lever 6 also has a pawl or tooth 15 which engagesthe locking-ratchet t on the paper-feedroll shaft. The pivotal orswinging arm T is provided with a graduated series of holes i in whichfits a stop-pin t, that serves to limit the throw of pawl-lever t andthus the extent of feed of the paper. By adjusting the stop-pin t todifferent. positions the space between the lines may be regulated, asdesired. The stop-pin t is mounted in a swinging arm or hearing tpivoted to the shaft 25 upon which the pawl-lever swings. The pivotal orswinging frame T that carries the paper-roller, is also provided with acurved shield or paper-guide T, upon which is j ournaled a smallfriction-roller T between which and the feed-roller the paper passes.This serves to insure a better and more convenient feed of the paper.The curved shield T is provided with a slot or opening for thefriction-roll T to project through and with a curved lip T The curvedshield T is provided with lips T", by which it is pivotally secured tothe swinging frame T by pivots or screws T and adjusting-screws Tconnected by springs T with the shield T near its upper edge, serve toadjust or regulate the pressure of the shield and its frictionroll Tagainst the paper-feed roll T For convenience in inserting the paper andalso to keep the paper from the mechanism below, the paper-carriage T isfurnished with a bot tom plate or guard T The paper-carriage is actuatedin the usual manner by a main spring in the drum if? IIO through theconnectingcord The papercarriage T is provided with an erasing-plate Tto form a smooth and firm support for the paper, and thus enableerasures and correct1ons to be made without removing the paper from themachine. The pivotal or swinging frame T is likewise provided with a.bar T having a handle T at its end. This bar T swlngs past theerasing-plate, and thus permlts the paper to lie down against the plate.This bar T also serves as a guard for the paper to prevent it lappingbackward over the hammer.

The escapement mechanism is substantiallythe same as in mypreviously-patented machine, and consists, briefly, of a shaft S,carrying a gear T, which meshes with the rack T on the paper-carriage T.The escapementshaft S is furnished with a sleeve S and a ratchet-wheel sand a clutch 5 The shaft S is also furnished with a sliding clutch .9held in place by a spring .9 which engages the clutch The shaft S isalso furnished with a sleeve 3 and a pin or crown wheel .9, having aslot .9 through which a pin 5 on the ratchet-wheel s before mentionedprojects. A spring 3 connects the pin 8 to the pin .9 on the back of theratchet'wheel s. The sliding clutch s" is actuated by a bent or thumblever,S which is held in place by a spring S The pin or crown wheel 3 isengaged by the pawl-lever M on the rock-shaft M. The pawllever M isoperated from the keys through the rock-shaft M, lever M, and rock-shaftG in the manner hereinbefore explained. The pawl-lever M is operateddirectly from the spacing-key V and lever V by the connectin g-link VPivoted to the main frame at P is a looking latch or pawl P which serveswhen pushed inone direction to engage and hold the cap-key lever O inits depressed or operating position and when pushed in the oppositedirection to hold the figure-key and key-lever P P in their depressed oroperating position.

Y is the bell, which is operated in theusual manner when the carriageTreaches thelimit of its movement.

0 is the stop for the lever O, and l? the stop for the lever P.

P is the spring for returning the levers O and P'to position.

- The lever M is provided with a pin m which spans the lever-arms h W,and thus serves to return said lever-arms to place.
